A complete front-wheel electric conversion kit built for the X3 AX trike. It pairs a 500W nominal front hub motor with a 48V 15Ah battery, a sine-wave controller and a 3.5-inch color SINET LCD with USB charging and diagnostics. You pick cadence or bottom-bracket torque sensing for pedal assist, and the kit includes model-specific battery mounting hardware. It suits X3 AX owners who want predictable low-speed assist on a trike rather than a universal kit that needs adapting.

This is a front-wheel electric conversion system made for the X3 AX trike. It uses the SINET platform with a 500W nominal front hub motor, an integrated sine-wave controller and a 48V 15Ah lithium-ion battery. The motor is built into a fixed 20" front wheel, so the trike's rear axle and drivetrain stay unchanged.
The battery slides into a SINET battery/controller cradle that houses the controller. X3 AX-specific mounting hardware holds the battery in place. A 3.5" full-color LCD shows battery voltage and level, current speed, trip meter and odometer. It also offers pedal-assist level selection, walk-assist mode, error diagnostics and an advanced programming menu. The LCD has a USB charging port.
Pedal assist comes with either a cadence sensor or a bottom bracket torque sensor. The cadence sensor detects crank rotation and does not measure rider force. It is the simpler installation. The torque sensor measures how hard you pedal and gives proportional assistance. It needs a compatible 68 mm square-taper bottom bracket, removal of the existing crank arms and bottom bracket, and a protected 3/8-inch cable-routing hole through the bottom bracket shell.
